Abstract
The invention discloses a kind of large blast furnace taphole mud sleeve integral production methods, include the following steps: S1, castable old in taphole frame frame all disintegrates before taphole mud sleeve is integrated poured, Hydraulic clay gun is operated to iron mouth region, big gun head lower edge is put in into 7-15mm in taphole frame frame, it is sealed in big gun head surrounding with steel form, edge opens up material filling mouth on steel form；It is S2, with blender that siccative is 2-4 minutes dry-mixed, the water of siccative weight 4%-6% is then added, is sufficiently stirred 3-5 minutes, obtains castable；S3, it is poured into taphole frame frame from material filling mouth by castable, until filling；S4, after filling castable, keep castable full with vibrating head slight vibration, by Hydraulic clay gun return after health 18-30 hours, it is covered 18-30 hours with small fire baking mud, being toasted 18-30 hours with high fire again can be used, it will not be pressed when method stifled iron notch of the invention and collapse mud set, long service life, and iron mouth is easy to maintain.
Description
Technical field
The present invention relates to a kind of large blast furnace taphole mud sleeve integral production methods.
Background technique
Currently, existing processing method is compacting mud set again that old mud set part is disintegrated, but due in mud set and iron
Castable cannot form an entirety inside mouth region, there are problems that the service life is low, difficult maintenance so as to cause it.
The taphole mud sleeve pouring procedure that No. 7 blast furnace opening initials of Baogang use is after old mud set to be plucked out to certain space with pouring
Material feeding casting, this mud set production method blast furnace intensity is low, low output in the case where, production is still maintained, as blast furnace is strong
Degree, output increased this mud set, which bear not live high temperature and pressure, to be influenced breakage often and causes to block up to run mud, and it is qualified to influence iron mouth depth
Rate.And service life is short to cause to switch that iron mouth is frequent, and stokehold labor intensity increases, it is difficult to meet large blast furnace production needs.
So the quality of mud set and service life are significant to blast fumance.
Summary of the invention
In order to solve the above-mentioned technical problem, the object of the present invention is to provide a kind of large blast furnace taphole mud sleeve integral manufacturing sides
Method.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of large blast furnace taphole mud sleeve integral production method, includes the following steps:
S1, castable old in taphole frame frame all disintegrated before taphole mud sleeve is integrated poured, by Hydraulic clay gun operation to iron
Big gun head lower edge is put in 7-15mm in taphole frame frame by mouth region, is sealed in big gun head surrounding with steel form, and edge opens up filling on steel form
Material mouth；
It is S2, with blender that siccative is 2-4 minutes dry-mixed, the water of siccative weight 4%-6% is then added, 3-5 is sufficiently stirred
Minute, obtain castable；
S3, it is poured into taphole frame frame from material filling mouth by castable, until filling；
S4, after filling castable, keep castable full with vibrating head slight vibration, by Hydraulic clay gun after health 18-30 hours
Return is covered 18-30 hours with small fire baking mud, then is toasted 18-30 hours with high fire and be can be used.
Further, Hydraulic clay gun is operated to iron mouth region and big gun head lower edge is put in into 10mm in taphole frame frame.
Further, with blender by siccative dry-mixed 3 minutes, then plus water 5%.
Further, health 24 hours are covered 24 hours with small fire baking mud, are toasted 24 hours with high fire.
Further, include the steps that purge in taphole frame frame after disintegrating clean.
Further, Hydraulic clay gun is operated to iron mouth region and big gun head lower edge is put in into 8mm or 12mm in taphole frame frame.
Further, with blender by siccative dry-mixed 2 minutes, then plus water 4%.
Compared with prior art, advantageous effects of the invention:
Method of the invention can successfully inhibit iron mouth region domain coal gas excessive after implementing, and keep taphole mud sleeve formation one solid
Integrally, it will not be pressed when stifled iron notch and collapse mud set, long service life improves whole ditch system iron and reaches 250,000 tons, and iron is switched in reduction
Mouth number, iron mouth is easy to maintain, effectively prevents the generation of all kinds of accidents.
Detailed description of the invention
Fig. 1 is old to pour preparation method effect diagram；
Fig. 2 is the effect diagram of method of the invention.
Specific embodiment
A kind of large blast furnace taphole mud sleeve integral production method will be old in taphole frame frame before taphole mud sleeve is integrated poured
Castable is all disintegrated, and will purge completely in taphole frame frame after disintegration, Hydraulic clay gun is operated to iron mouth region and puts in big gun head lower edge
10mm in taphole frame frame is sealed in big gun head surrounding with steel form, and material filling mouth is opened on edge on steel form, with blender that siccative is dry-mixed
Then plus water 4%-5% it 2-3 minutes, is sufficiently stirred 3-5 minutes, is poured into taphole frame frame from material filling mouth by castable, directly
Until filling.After filling castable, keep castable full with vibrating head slight vibration, then returns Hydraulic clay gun within health 24 hours
Position is covered 24 hours with small fire baking mud, then is toasted 24 hours with high fire and be can be used.
Health and large and small fire in the present invention control the conventional technical means being well known to the skilled person,
This is not repeated specifically, if be those skilled in the art can make according to actual needs adjustment, be ensured of health after
It can be achieved the goal with small fire and high fire baking respectively.
In October, 2017 in No. 1 iron mouth practical application of No. 7 blast furnaces, in January, 2018 in 7,8 blast furnace institutes after success of the test
There are the popularization and application of iron mouth, so far 7,8 blast furnace taphole good application effect.
As shown in Fig. 2, its using effect is good., then see Fig. 1, it is old pour the new and old material of preparation method and combine cause gas leak tight
Weight.
Embodiment described above is only that preferred embodiment of the invention is described, and is not carried out to the scope of the present invention
It limits, without departing from the spirit of the design of the present invention, those of ordinary skill in the art make technical solution of the present invention
Various changes and improvements, should all fall into claims of the present invention determine protection scope in.
